The Four Seasons
According to Vincent van Gogh, summer is the most challenging season for a painter. He reported to his brother Theodor (in the third volume of his "Sämtliche Briefe", pages 182-183): "But I mean it isn’t easy to find the effect of a summer sun that’s as lush and as simple and as pleasant to look at as the characteristic effects of the other seasons. The spring is tender green (young wheat) and pink (apple blossom). The autumn is the contrast of the yellow leaves against violet tones. The winter is the snow with the little black silhouettes."
The undated letter dates from the period between December 1883 and November 1885. Later, under the scorching sun, van Gogh devoted himself with preference to the shimmering summer light of southern France - and it is not least these pictures that established his fame. Now, it is interesting that his "solution" is already found in the letter quoted, indeed he presents a whole colour theory of the seasons in it: "But if the summer is the opposition of blues against an element of orange in the golden bronze, of the wheat, this way one could paint a painting in each of the contrasts of the complementary colours (red and green, blue and orange, yellow and violet, white and black) that expressed the mood of the seasons" - several pictures from his famous late work come to mind, the waving yellow-orange grain fields under a deep blue sky.
Thus, blue and orange were the colours of summer for Vincent van Gogh. Whatever your colour of summer is (by dominating your summer garden as a flowering plant splendour, for example) - enjoy the seasons and enjoy the art of ars mundi.
